Definitions
- the device according to the invention and the method according to the invention for contactless rotation angle detection of a rotatable element have the advantage that, due to an increased resolution, definite rotation angles over a plurality of revolutions of the rotatable element are detected or determined with a very high accuracy and an increased susceptibility to interference can be.
- the position of the plunger within the coil can be detected by means of a resonant circuit whose resonance frequency depends on the coil inductance. In this way, a very interference-proof rotation angle detection is ensured, the position resolution depending on the sampling rate during the measurement of the resonant frequency associated period can be increased almost arbitrarily.
- the plunger core 30 moves relative to the coil 31 but also the coil 31 relative to the plunger core 30, ie the coil 31 is either alone or in combination with the plunger core 30 via the shafts 20 and 36, respectively suitable means, such as pinions, etc., set in motion.
- suitable means such as pinions, etc., set in motion.
- the device according to the invention and the method according to the invention are not limited to an application in conjunction with an electric power steering drive, but can also be used for multiturn rotation angle detection of other, rotatable elements.
